Has there been any thought in spending some time cleaning up the code to try
and stop these assumptions all over the place and create some better
abstractions? Clearly cyrus has been a project that's evolved over time, and
the code is where it is now because of the evolution over time, but some
time spent fixing old assumptions and some old programming practices would
certainly help with the speediness and correctness of future coding?
